To enable metering and the display of certain metrics by the MapR Control System (MCS), you must install collectd and
OpenTSDB components. Metrics monitoring is part of MapR Monitoring, which also includes log monitoring. MapR Monitoring components are
available as part of the MapR Ecosystem Pack (MEP) that you selected for the cluster.

You can apply a patch by using the MapR Installer, by using the command line (a manual process), or by using a MapR Installer
Stanza.

Installing without the MapR Installer

Describes how to install MapR software and ecosystem components manually.

These steps describe how to install a secure MapR cluster. If your cluster does not need to
be secure, you can still use this procedure and skip over the steps indicated for
security.

After you have planned the cluster and prepared each node, you can install the MapR
distribution from the MapR repository or package files. Installing MapR requires that you
perform certain steps on each node. You can install Apache Ecosystem components, such as Hive,
after you bring up the cluster.

Warning: Before you install, make sure that all nodes meet the requirements for
installation. See Preparing each Node for more information. Failure to
prepare nodes is the primary cause of installation problems.

You must also make sure
that theMapR Installer package dependenciesare installed. These packages are downloaded for you when you use the MapR Installer, but
must be installed manually before you install without using the MapR
Installer.

You must also have the following information from your cluster plan when you install:

A list of the hostnames (or IP addresses) for all nodes and the services that you want
to run on each node.

Step 7: Bring up the Cluster
Before you can install metrics monitoring, log monitoring, or ecosystem components, you must enable the cluster by starting ZooKeeper and Warden and verifying the cluster installation status.

Step 8: Install Metrics MonitoringTo enable metering and the display of certain metrics by the MapR Control System (MCS), you must install collectd and OpenTSDB components. Metrics monitoring is part of MapR Monitoring, which also includes log monitoring. MapR Monitoring components are available as part of the MapR Ecosystem Pack (MEP) that you selected for the cluster.

Step 9: Install Log Monitoring
Installing the logging components of MapR Monitoring is optional. MapR Monitoring components are available as part of the MapR Ecosystem Pack (MEP) that you selected for the cluster.

Step 10: Install Ecosystem Components Manually
You can install one or more ecosystem components from any MapR Ecosystem Pack (MEP) that is supported by the MapR cluster version. A MEP consists of a group of ecosystem components that work together.

Step 11: Run configure.sh
Run configure.sh with the -R option to complete the configuration of ecosystem components that were added manually.
